A superstrate, such as a sheet of polymer film (310), is used as a transport during metallization of solar cells (130). The back sides of the solar cells (130) are attached to the sheet of polymer film (310). Contact holes are formed through the sheet of polymer film (310) to expose doped regions of the solar cells (310). Metals are formed in the contact holes to electrically connect to the exposed doped regions of the solar cells (130). The metals are electroplated to form metal contacts (354, 355) of the solar cell (130). Subsequently, the solar cells (130) are separated from other solar cells that were metallized while supported by the same sheet of polymer film (310) to form strings of solar cells or individual solar cells. |
